I've quoted those lines where you lost your 2nd solution.
A product of two factors is zero, if one factor is zero:
So you get:
After solving both equations you've got all possible results.
I have a problem again with irrational equation.
I have to solve this equation:
I have solve it like this:
This is one solution but there is another one that is not obvious: .
Now, I have come to that solution by assuming that right side of equation is 0:
Can someone explain me how to know exactly what are ALL solutions of irrational equations?
